San Diego  The expansion of the Flower Hill Promenade near Del Mar is on the brink of final approval.

The proposed renovation will advance to the San Diego City Council, likely next month, with the support of the city’s planning commission.

The commission, which serves in an advisory role to the council, voted 4-2 Thursday to support the renovation. The Flower Hill Promenade is just east of Interstate 5 on Via de la Valle, technically in San Diego. It neighbors Solana Beach and Del Mar.

The project calls for a 72,695 square-foot commercial and office building that would include a 35,000 square-foot Whole Foods Market, 25,000 square-feet of office space and 8,700 square-feet of retail shops, project spokesman Chris Wahl said. Whole Foods has signed a lease for the space, but no other retail tenants have been inked, Wahl said Friday.

The project also would include an 83,739-square-foot four-level parking garage. The Ultrastar Movie Theatre would be demolished. The mall’s expansion has not gone unopposed. It went through six years of planning, presentations and adjustments, and in August finally received support from the Carmel Valley Planning Board, an advisory panel to the San Diego Planning Commission.

A key reason for the planning board’s 11-3 vote was the support of the homeowners association of the adjacent Spindrift housing complex, which uses Flower Hill Drive as a major access road to the complex.

A group called Citizens Against Flower Hill’s Excessive Expansion formed to fight the project. It said the development was too intense for the surrounding coastal wetlands. The expansion would result in a net increase of 61,000 square feet of mall space, less than half of what was originally proposed.

If the City Council approves the project, construction could begin in June, Whal said.
